The "Liquid Tree" is Very Cool Actually (youtu.be)

Scientists in Belgrade came up with the idea of "planting" large tanks of water and algae in places where trees can't grow. The tanks are 10-50x more efficient than a normal tree for the space it takes up and is in general highly sustainable, even creating excellent fertilizer in the process. You can skip about halfway through the video for the actual information about them.

Sure, it's cool, but I can't sit underneath it if I'm trying to get out of the sun. Maybe in the afternoon, but certainly not midday. Idk, trees are obviously suited to land but these are cool public art pieces, plus they're sustainable and sinks CO2 (but who knows how clean construction is).

I'm sure it could be but into horizontal panels, for instance the roof of a bus stop. Also probably in tubes for larger partial-shade configurations (like a pergola).

That and obviously it should be in addition to trees rather than a replacement.

yes all the negativity in the thread is making the false supposition that you have to choose between an algae tank and trees. the choice is an algae tank or no algae tank.

That's looking at it as a zero-sum thing. You're not choosing between an algae tank and a utopian solarpunk city with no cars, tree lined streets, and bikes and grassy trams every where. You're choosing between an algae tank and all its benefits, or no algae tank. I would choose the algae tank over nothing any day. Would I take it in place of a perfect solarpunk city where we all live in trees and get around with rope bridges? hell no.
